H05V-K and H07V-K Flexible Cable Applications
H05V-K and H07V-K are harmonized (HAR), single-core, flexible PVC insulated wires designed for internal wiring in switchgear, control panels, electronic equipment, and lighting fixtures. Manufactured under the harmonized standard EN 50525-2-31 (formerly HD 21.3), these cables feature a Class 5 fine-stranded annealed copper conductor to facilitate easy routing in tight spaces.
- H05V-K (Rated Voltage 300/500V): Exclusively utilized for internal wiring of control equipment, signaling circuits, instrumentation loops, and protected installation inside appliances or lighting tracks.
- H07V-K (Rated Voltage 450/750V): Engineered for higher power demands, including power distribution panels, motor circuits, conduits, and closed cable trunking systems in both industrial and commercial automation setups.

Core Characteristics and Compliance
Key Features of H05V-K & H07V-K Cables
- High Flexibility: The Class 5 fine-wire layout enables consistent flexing without mechanical fatigue, optimizing layout density inside complex automation matrices.
- Oil and Chemical Resistance: The specialized PVC compound provides basic resistance to industrial oils, acids, and alkalis typical in factory floor environments.
- Flame Retardancy: Self-extinguishing properties under IEC 60332-1-2 prevent vertical flame propagation along the cable run during localized thermal faults.
Global Standardization Compliance
These products conform strictly to the European Harmonization Document (HAR system), simplifying cross-border machine design and guaranteeing adherence to CE, RoHS, and REACH directives. This structural uniformity ensures that any H05V-K or H07V-K cable integrates seamlessly into international PLC cabinets, MCC panels, and machine-tool designs without requiring regional recalculation of current-carrying capacities.
